Seven months of work, most of it on cold nights
Your furnace runs from October through April here, seven months of the year. On winter nights that average 28°F, it cycles on and off again and again to hold the house steady. Each start puts the load on the igniter, the part that has to light the burner every single time. Wear one down and it stops lighting, or lights late, and the burner won't fire.
Payne County also sees its share of winter storms and wind, seven winter storms and 83 damaging wind events over the past ten years. Storms knock out power, and a furnace with no power will not run no matter how sound it is. Across Oklahoma, a quarter of households lost power for at least 24 hours in 2024. When the power comes back, most furnaces restart on their own, but if yours does not fire back up, that is worth a call.

Oklahoma requires HVAC contractors to hold a state license.
That license comes from the Construction Industries Board. Getting one means the contractor was tested and is on record with the state. It covers the contractor, not the job, so the same license that qualifies someone to install a furnace also covers repairing one.
For a furnace repair, the gas connection is the part that matters most. A loose fitting or bad seal there is the real danger in this kind of work, and in Oklahoma that work falls under a contractor who has already been tested and licensed by the state to do it.

- Why won't my furnace turn on?
- Most often the thermostat isn't calling for heat, or power to the furnace has been cut off somewhere. Check that the thermostat is set to heat and the temperature is above room temperature. Check the furnace switch, which looks like a light switch near the unit, and the breaker for it. If those are fine, the igniter or a safety switch inside the furnace may have failed, and that calls for a contractor to check.
- Why is my furnace blowing cold air?
- The blower may be running before the burners have lit, which is normal for a short stretch after the thermostat calls for heat. If cold air keeps coming for more than a few minutes, the igniter or gas valve likely isn't lighting the burners even though the fan runs. A clogged filter can also cause this by starving the burners of the airflow they need to stay on. If changing the filter doesn't fix it, a contractor will need to look at the ignition system.
- Why won't my furnace pilot light stay lit?
- A pilot that won't stay lit is usually a worn thermocouple, the small sensor that tells the gas valve the flame is burning. When it fails, the valve shuts the gas off as a safety measure even though the pilot lit fine. Wind or a draft in the vent can also blow the flame out, so check for anything blocking or disturbing the vent. If relighting it doesn't hold, the thermocouple likely needs replacing, and that's a job for a licensed contractor.
